Question

Give me step by step answer ​

Answer 1

Answer:

Let the number be x

Acc. To condition

X + 7/8 = -4/5

X= - 4/5-7/8

X= - 32 - 35 /40

X= - 67/40

Step-by-step explanation:

-67/40 + 7/8 = - 4/5

-67 + 35/40 = - 4/5

-32/40= - 4/5

If you simplify - 32/40 you will get - 4/5

L.H.S = R.H.S

HENCE,-67/40 Should be added to 7/8 to get - 4/5

Answer 2

Step-by-step explanation:

let x be the number

7/8 +x = (-4/5)

-x = 7/8 +(4/5)

= [(7x5) + (4×8)]/ 40

(by taking l.c.m for 8 and 5 is in fig )

- x = (35+32) /40

- x = 67/40

× = -67/40
